as part payment for a roadbike i took a bianchi pista 57 cm and thought i could stretch a bit. well i cant and am looking for an exchange with someone who has a 55 or even a 53 with a strong seatpost. as per factory except for drilled fork and brake with hard to spot small/discreet bmx lever. will consider other good cond. single speed. may be interested in hot road bike frame but prefer all things italian.
